Supplementary textbook for learning basic knowledge about radiation. - Title: Supplementary Textbook on Radiation for Junior High and High School Students - Publication Date: September 2018 - Publisher: Ministry of Education, Culture, Sports, Science and Technology - Table of Contents: Basic knowledge of radiation, the role of nuclear power plants and their environmental impact, etc. This supplementary textbook was suddenly distributed at school around the time that the nuclear power plant issue was being reported daily in the news. It wasn't used for studying specifically, but rather, "Please read it at home," was what we were told, so we brought it home. It's unused, but there are some creases and wrinkles from the child bringing it home, so I chose "Like New." It's a booklet for children, but I think it's good for adults too. It was created based on the government's policy as of 2018, but it also contains basic knowledge, so I recommend it for personal learning.
